ESR spectra of ferricytochrome c paramagnetic centers induced by UV-light at 77 K
Description
Paramagnetic properties of ferricytochrome c aqueous glyceric solutions exposed to UV-light of various wave lengths at 77 K have been investigated. Absorption of long-wave UV- and visible light by hemin (5-240 min) does not induce the formation of paramagnetic centres in hemoproteid. However absorption of UV-light by chromoforms of a protein component of ferricytochrome c induces the formation of free radicals with a quantum yield of 0.07. During long-term (40 to 200 min) UV-irradiation (260-380 nm) of protein solutions several types of paramagnetic centres including HCO radicals are formed
